BY '2, ATTORNEY/l Patented Jan. 14,. 1930 DOMINICK J. CALDERAZZO, OFBROOKLYN, NEW YORK BUILDING WALL, MATERIAL, AND METHOD OF MAKING SAMEApplication filed November 30, 1928. Serial No. 322,608.

This invention relates to building walls. More particularly it isdirected to a wall surfacing simulating brickwork and the like and themethod of making the same.

An object of this invention is to provide a simple and economicalprocess for finishing stucco walls and the like to give the same a widevariety of highly decorative effects such as simulated brickwork and thelike.

A further object of this invention is to provide an improved buildingWall of the character described which shall be compact and rugged inconstruction, which shall be finished in a highly-decorative manner andyet be practical toa high degree.

' Other objects of this invention will in part be obvious and in parthereinafter pointed out.

The invention accordingly consists in the features of construction,combinations of elements, and arrangement of parts which will beexemplified in the construction hereinafter described, and of which thescope of application will be indicated in the following claims.

In the accompanying drawing, in which 1S shown one of the variouspossible illustrative embodiments of thls invention,

Fig. 1 is an elevational view of a wall made in accordance with theinvention with portions broken away to show the various layerscomprising said wall.

Fig. 2 is a section on the line 22 of Fig. 1.

Referring in detail to the drawing, 10 designates a portion of a wallembodying the invention. Said wall comprises the usual wire netting 11secured to any suitable backing such as wood siding (not shown).Covering said netting 11' is a layer 12 of stucco, rough cement ormortar. -This layer of cement. provides a backing for a relatively thinlayer 13 of cement and mortar colored in any suitable manner as bymixing with paint. Said layer 13 .may be applied by trowelling or in anyother manner suitable for providing a smooth even surface 14. If desiredthis layer may be applied in its material color, that is, in the naturalcolor of the material. A second layer 15 of cementitious material 60preferably mixed with a paint contrasting with the color of layer 13, isapplied over the latter layer. Said layers 13 and 15 are ofsubstantially equal thickness and are of simi-. lar material andsimilarly applied, except that said layers are made with contrasting acolor contrasting with the colors of both layers 13 and 15, and ispreferably of the color that bricks. are usually made of. To produce alasting coating, the paint may be 05 mixed with fine cementitious'materiall The resulting material must be of such consistency as topermit brushing the same over layer 15.

To produce a finish simulating brickwork, the outer layer of paint 16may be grooved or chiselled in any suitable manner to reveal theadjacent layer 15. Horizontal lines 17 and vertical lines 18 may be thuscut out to make a design of brickwork .19 since the ,grooves present acolor contrasting with that of the outer coating. If desired, thegrooves may be made deeper as shown at 20 to reveal the layer 13 andthus produce a different color for simulating the mortar joints betweenthe bricks.

Effects other than brickwork may be pro duced by suitably cutting orgrooving the outer layer in any desired design. Further, highlydecorative effects may beproduced by exposing portions of both layers 13and 15.

The decorative appearance of the brickwork may be enhanced by applyingscattered irregular colored spots to the outer coat 16 to give theeffect of colored pebbles or stones mixed in the bricks. Such spots 21are pref- 90 erably applied to said outer layer before the groovingoperation.

' It will thus be seen that there is provided a device in which theseveral objects of this invention are achieved, and which is well 9adapted to meet the conditions of practical use. I

As various possible embodiments might be made of the above invention.and as various changes might be made in the embodiment set 1% forth, itis to be understood that all matter herein set forth or shown in theaccompanying drawing is to be interpreted as illustrative and not in alimiting sense.

Having thus described my invention, I claim as new and desire to secureby Letters Patent: v

1. The process of finishing building walls which consists of applying alayer of colored cementitious material to said wall, and applying oversaid layer a coating of paint of a color contrasting with that of saidlayer, and thereafter removing portions of said coating to revealportions of said layer to produce a design.

2. The process of finishing building walls which consists of applying alayer of colored surfacing material to said wall, thereafter applying asecond layer of colored surfacing material over said first layer andthereafter applying a coating of paint over the outer layer, the colorsof said layers and coating contrasting with one another, and thereafterremoving portions of said coating to reveal .portions of said outerlayer in predetermined design.

3. The process of finishing building walls which consists of applying alayer of colored surfacing material to said wall, thereafter applying asecond layer of colored surfacing material over said first layer, andthereafter applying a coating of paint over the outer layer, the colorsof said layers and coating contrasting with one another, and thereafterremoving superimposed portions of said coating and outer layer to revealportions of said inner layer to produce a design.

4. The process of finishing building walls which consists of applying alayer of colored surfacing material to said wall, thereafter applying asecond layer of colored surfacing material over said first layer andthereafter applying a coating of paint over the outer layer, the colorsof said layers and coating contrasting with one another, and thereafterremoving portions of said coating to reveal portions of said outer layerand removing superimposed portions of said coating and outer layer toreveal portions of said inner layer to produce a decorative effectshowing portions of said layers and coating in predetermined design.

5. The process of finishing building walls which consists of applying alayer of colored surfacing material to sa d wall, thereafter applying asecond layer of surfacing material having a color contrasting with saidfirst layer over the latter, thereafter applying a coatin of paint havina color contrasting with t at of both said layers over the outer layer,thereafter a )plying irregularly scattered spots of sur acing materialhaving a color contrasting with that of said coating over the latter,and thereafter removing portions of said coating to reveal portions ofsaid outer layer and removing superimposed portions of said coating andsaid outer layer to reveal portions of said inner layer to produce adecorative effect showing portions of said layers and spotted coating inpredetermined design.

6. In a building wall of the character described, comprising a layer ofstucco, a layer of colored cementitious material superimposed over saidfirst mentioned layer and a coating of paint superimposed over saidouter layer, said coatin having cut-away portions for exposing sai layerof cementitious material in predetermined design.

7. In a building wall comprising a layer of relatively roughcementitious material, a plurality of superimposed layers ofcontrastingly colored cementitious material, and a coating of paintsuperimposed over said layers, portions of said coating being cut-awayto expose the outer layer of cementitious material, and additionalsuperimposed portions of said coating and outer layer being cut-away forexposing said portion of another layer of cementitious material forexposing a plurality of colors in predetermined relief design.

In testimony whereof I afiix my signature.
